There's a few of us who dig these pickups, maybe this might help share the info we have on them.
I myself think these are great sounding pickups (and cheap!!!), and also as far as my experience dealing with Wilde, they are very serious to deal with.
One thing to note though is I believe that while they have good communication, they might not be so good answering emails. I personally believe that being email a relatively new means of communication, and being Wilde a family business, this is quite understandable. They do give their phones if you need them.
And while I've seen some complaints mostly of people not being informed when their pickups would arrive, I have not heard not even one complaint about the product itself or somebody not receiving their order.

Review of the p-46 thread: Bill Lawrence P-46 Pickup mini review (BEST P Pickup I've EVER tried)!
I believe most the info is in that thread.
there's quite a few other threads but they might not be so easy to find, add them if you think they might be helpful.
And if you have a Wilde pickup on any of your instruments, please, PLEEEASEEEE post soundclips!!!!!!
